As shown in fig. 7, in some embodiments, the atomizer 3 of the atomizing body 20 includes an atomizing assembly 32 and an outlet 33 for allowing the aerosol atomized by the atomizing assembly 32 to flow out.

Referring to fig. 1, 2, 7 and 8, when the switch assembly 1 is in the first position B, the outlet 33 is blocked, when the switch assembly 1 is in the second position C, the outlet 33 is opened, and after the atomization assembly 32 is energized, the atomized liquid is atomized by high-frequency vibration, and the aerosol formed by atomization is discharged from the outlet 33.

Preferably, a cover 34 may be provided on the outlet 33, and when not in use, the cover 34 covers the outlet 33 to prevent the atomized liquid inside from flowing out.

As shown in fig. 8 and 9, when the atomizer 3 is turned off, that is, the switch assembly 1 slides to the first position B, and the first magnetic member 11 is away from the first hall module 23, the first hall module 23 controls the switch 221 to be turned off, and at this time, the power supply 22 only supplies power to the first hall module 23, so that the power consumption of the atomizer 3 can be saved; when the atomizer 3 is turned on, that is, the switch assembly 1 moves to the second position C, and the switch assembly 1 drives the first magnetic member 11 to be close to the first hall module 23, the first hall module 23 controls the switch 221 to be turned on, so as to supply power to the controller 21 and the second hall module 24.

The first hall module 23 and the second hall module 24 may both be digital hall sensors, or the first hall module 23 is a digital hall sensor and the second hall module 24 includes a linear hall sensor.

The first hall module 23 is used for controlling the power-on/off of the second hall module 24, and the second hall module 24 is used for controlling the atomizing main body 20 to start/stop atomizing work.

When the switch assembly 1 slides to the second position C, the first hall module 23 controls the second hall module 24 to be powered on, and when the second hall module 24 senses the second magnetic member 12, the atomization main body 20 is controlled to start atomization work; when the switch assembly slides to the first position B, the second hall module 24 controls the atomization main body 20 to stop atomization work, and the first hall module 23 controls the second hall module 24 to be powered off.

When the external interference magnetic field interferes with the first hall module 23, the system does not detect the change of the hall, the atomizer 3 does not work, when the switch component 1 slides to the first position B, the second hall module 24 detects the change, the work of the atomizing sheet 323 of the atomizer 3 is quickly turned off, the first hall module 23 controls the control switch 221 to be cut off, the controller 21 and the second hall module 24 are powered off, further, because the second hall module 24 is a digital hall sensor, the atomization main body 20 stops atomization, and the second hall module 24 is powered off.

In other embodiments, the first hall module 23 is a digital hall sensor and the second hall module 24 is a linear hall sensor. When the switch assembly 1 slides to the second position C, the power supply 22 is turned on, the first hall module 23 senses the first magnetic part 11 to control the control switch 221 to be turned on, the first hall module 23 turns on the power supply 22, the second hall module 24 senses the magnetic field intensity of the second magnetic part 12 to control the atomizing main body to start atomizing work through the controller 21, and if there is other magnetic field interference, the second hall module 24 can judge whether there is other interference according to the detected magnetic field intensity; when the switch component 1 slides to the first position B, the second hall module 24 controls the atomization main body 20 to stop atomization, the first hall module 23 controls the second hall module 24 to be powered off, further, the second hall module 24 is a linear hall sensor, the atomization main body 20 stops the second hall module 24 to be powered off after atomization, the atomization driving is quickly turned off according to the magnetic field change of the second hall module 24, and atomization is prevented from being not timely turned off to cause effusion at an atomization port.

When the second hall module 24 is a linear hall sensor, since the linear hall sensor outputs a control signal by detecting the strength of the magnetic field, the linear hall sensor can output a control signal earlier than the digital hall sensor, thereby turning off the atomizing assembly 32 in advance. That is, if there are two digital hall sensors, the power off and the closing of the atomized spray are performed simultaneously, and a linear one number is used, the closing of the atomized spray first and then the power off can be realized.

The invention also provides a linear Hall device self-adaptive algorithm of a double-Hall mistake-proofing atomization structure, wherein the first Hall module 23 is a digital Hall sensor, the second Hall module 24 is a linear Hall sensor, and the algorithm comprises the following steps:

when the switch component 1 moves to the first position B and is opened, the controller 21 detects that the first Hall module 23 outputs an effective level, and at the moment, atomization is started and the output voltage value of the second Hall module 24 is sampled;

after the voltage output of the second hall module 24 is stable, sampling the output voltage V value of the second hall module 24 as the voltage output high value Vh of the second hall module 24;

the atomization is on/off controlled by subtracting the set voltage from the voltage output high value Vh as the on/off threshold of the second hall module 24.

In general, the average value of the output voltage of the second hall module 24 within a set time is calculated as the output voltage high value Vh of the second hall module 24, and a set voltage is subtracted from Vh as the switch detection threshold Vt, and preferably, in the present embodiment, the set time is 100 ± 10 ms.

According to different atomization devices, AD of the output voltage V of the second Hall module 24 is between 2100 and 2400.

Preferably, the voltage is set to be 60, and the high value minus 60 AD values are used as a switching threshold value, so that the positions of the switching components can be basically consistent when different atomization devices are atomized to be switched on/off, and the sensitivity can be ensured to be consistent.

The light source emits light in a direction opposite to the end of the light guide head 282, so that the light can sufficiently enter the light guide head 282. Preferably, the light guide plate 281, the light guide head 282 and the light emitting flange 283 are integrally formed, and are made of a transparent material, usually plastic, which can prevent light absorption.

Preferably, the light emitting surface of the light emitting flange 283 is a cambered surface, which can increase the light emitting range, and of course, the light emitting surface can also be a prismatic surface. Further, the light emitting range of the light emitting surface is not less than 175 °, so that the light emitting range is large.

A chamfer I is formed between the root of the light guide head 282 and the light guide plate 281, and the outer edge of the light guide plate 281 on the same side with the light guide head 282 is provided with an oblique angle J, and the chamfer I and the oblique angle J are arranged to enable incident light rays to be better guided into a light guide path.

In this embodiment, the light guide plate 281 is circular, and the ratio of the diameter of the light guide plate 281 to the height H of the light guide head 282 is 10: 1-15: 1. in other embodiments, the light guide plate 281 may not be circular, for example, square, polygonal, etc. and the ratio of the length of the long side of the light guide plate 281 to the height of the light guide head 282 is 10: 1-15: 1.

the ratio of the thickness H of the light guide plate 281 to the width N of the light emitting surface is 0.9-1.1, so that the light emitting effect is better. If it is too wide or too narrow, energy loss at the time of optical path switching becomes large, and light emission luminance becomes weak.

The light emitting surface of the light emitting flange 283 is formed with a texture, and the concave-convex texture structure is formed by a surface treatment process such as a texturing treatment process, so that the diffusion range of light passing through the surface can be increased.

The area of the end surface of the light guide head 282 is not smaller than the area of the light emitting surface of the light source on the end surface of the light guide head 282, and the light of the light source can be sufficiently led out from the light guide head 282.

Further, one side of the light guide plate 281, which is opposite to the light guide head 282, is provided with a concave light guide hole 284, and the light guide hole 284 can radiate a light path outwards and lead out to a light emitting surface to emit light through a peripheral oblique angle.

Preferably, the light guide hole 284 is tapered to radiate light to the periphery, and the light guide hole 284 may be a cold taper or a round taper.

The ratio of the depth of the light guide hole 284 to the thickness of the light guide plate 281 is 1 to 1.5, so that light can be more sufficiently radiated by the light guide plate 281.

Further, the light guide hole 284 is concentric with the light guide head 282, in this embodiment, the light guide hole 284 is disposed eccentrically, and the light guide hole 284 is preferably disposed at the center of the light guide plate 281.

It is to be understood that the above-described respective technical features may be used in any combination without limitation.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
